文章通过建立一简单的电偶极子模型，从理论上研究和探讨红皮云杉冠层表面光的散射分布以及表面的光能分布。引入表面空隙度这一新概念，描述在冠层表面中介质（枝叶）分布状况。理论结果表明，冠层表面散射光强的影响很小，它的强度近似于原入射光强的０５％。因此，在单木冠层表面的各个侧面，每个侧面表面光能分布近似均匀的，并且各个侧面的光能分布不同，其中与光入射方向垂直的哪个侧面分布最强。
In this paper, we establish a simple electric dipole model to study and investigate the scattering distribution of surface light and the light energy distribution of the surface of spruce. The introduction of the new concept of surface porosity describes the distribution of media (foliage) in the canopy surface. The theoretical results show that the influence of the light intensity on the canopy surface is very small, and its intensity is close to 05% of the original light intensity. Therefore, the light energy distribution of each side surface is approximately uniform on each side of the single-wood canopy surface, and the light energy distribution of each side is different, and among which the side surface perpendicular to the light incident direction is the strongest.
